"It is said, lord, 'becoming, becoming.' In what way, lord, is there becoming?"
"if, Ananda, there were no kamma ripening in the sense realm, would sense-sphere becoming be discerned?"
"No, lord."
"Thus, Ananda, kamma is the field, consciousness is the seed, craving the moisture; for beings obstructed by ignorance and fettered to craving, consciousness becomes grounded in a low realm. Thus, Ananda, there is the production of re-becoming in the future. It is thus, Ananda, that there is becoming.
"If, Ananda, there were no kamma ripening in the fine-material realm, would fine-material becoming be discerned?"
"No, lord."
"Thus, Ananda, kamma is the field, consciousness is the seed, craving the moisture; for beings obstructed by ignorance and fettered to craving, consciousness becomes grounded in a middling realm. Thus, Ananda, there is the production of re-becoming in the future. It is thus, Ananda, that there is becoming.
"If, Ananda, there were no kamma ripening in the immaterial realm, would immaterial becoming be discerned?"
"No, lord."
"Thus, Ananda, kamma is the field, consciousness is the seed, craving the moisture; for beings obstructed by ignorance and fettered to craving, consciousness becomes grounded in a superior realm. Thus, Ananda, there is the production of re-becoming in the future. It is thus, Ananda, that there is becoming."
